Summaries
Gene Snapshot
Mitochondrial aconitase 1 (mAcon1) encodes an enzyme that harbors an iron-sulfur cluster and catalyses the first step of the Krebs Cycle in mitochondria, converting citrate into isocitrate. [Date last reviewed: 2018-09-13]
Gene Group (FlyBase)
ACONITASES -
Aconitases catalyze the stereo-specific isomerization of citrate to isocitrate via cis-aconitate. They comprise mitochondrial aconitases that function in the tricarboxylic-acid cycle, and cytosolic aconitases that also function as iron-regulatory proteins.

Model Confidence:
  • Very high (pLDDT > 90)
  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)
  • Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

        Nomenclature History

        Source for identity of: mAcon1 Acon

        Nomenclature comments

        Renamed from 'Acon' (Aconitase) to 'mAcon1' (Mitochondrial aconitase 1) to reflect that this is a mitochondrial, rather than cytoplasmic, aconitase. This is consistent with the nomenclature used for this gene/protein from several publications. Added a '1' suffix to distinguish it from the other, less studied mitochondrial aconitase (CG4706/mAcon2) that is mainly expressed in the testis (see FBrf0221188).
